Campanula grows a rosette of leaves the first year. That means leaves spread a bit but close to the ground. The second year it will send up flower stems from that rosette of leaves.

The flowers look like a cup and saucer with a bell shaped center and a ruffle of petals behind the bell.

I don't have a photo but I have grown them. If you started them early enough it may bloom late in summer.

If what you planted starts to grow taller in the early stages it won't be campanula. Look for a bunch of leaves close to the ground

How about posting a picture of what you have growing and we can tell you if they are Canterbury Bells?

When re-using potting mix you need to be sure that something totally different than what was in it first gets planted in it. Especially with flowers. Use that to plant peppers or tomatoes for example.

Here is a link to a photo.

Ooh, thanks!!! I will try to post a pic. I have a good feeling so far. They're still really tiny and not growing very fast at all, but I'm hopeful.

Okay, I'm trying to put up a photo now.

I guess you can only do one?

That is not campanula. The leaves are too fleshy and not the right shape. It looks more like a balsaam or begonia

I'm not sure what the scale is on that picture but it could well be Hairy Bittercress, Cardamine hirsta, which I am afraid is an annoying weed.

Thanks for the help! I *do* have that weed growing around, as it happens.

I made a mistake when I planted the Canterbury seeds. The Burpee package said to bury them, but then I saw online, it should have been surface sown. I guess their tiny size should have been a clue.

I will keep watering and hope for the best anyhow, you never know. I tried to unbury them but the seeds are so tiny.

Now, what about this? It looks too big to have come out of that tiny seed though.

These are my baby Canterbury Bell seedlings. Planted Feb 19. For reference, the pot is only about an 1 3/4 inches square. And the orange stick is a broken half of a round toothpick. The seedlings are quite small.

But, they are tough little seeds. Mine were actually from a Burpee pack from 2011 and they still sprouted fine. I looked at the pack and (at least on the one I have) they recommend putting the seeds 1/4 inch down. If you only went that far, they should be fine.

Mine took somewhere between 1 and 2 weeks to sprout at temps around 70-75.

My babies have only just started on their real leaves, so no rosettes or anything yet...but the pic might help you with earlier identification. The sprout leaves are fat triangles, and the little real leaves have hairy looking edges.

Thanks so much, SaraElise!

I do have a couple things that *might* turn out to be winners. I'm going to keep watering and see what happens.
